Obesity remains a serious health problem and it is no secret that many people want to lose weight. Behavioral economists typically argue that “nudges” help individuals with various decisionmaking flaws to live longer, healthier, and better lives. In an article in the new issue of Regulation, Michael L. Marlow discusses how nudging by government differs from nudging by markets, and explains why market nudging is the more promising avenue for helping citizens to lose weight.

Two long wars, chronic deficits, the financial crisis, the costly drug war, the growth of executive power under Presidents Bush and Obama, and the revelations about NSA abuses, have given rise to a growing libertarian movement in our country – with a greater focus on individual liberty and less government power. David Boaz’s newly released The Libertarian Mind is a comprehensive guide to the history, philosophy, and growth of the libertarian movement, with incisive analyses of today’s most pressing issues and policies.

Sotomayor Confirmed, Constitutional Debate Continues

All Americans should take pride in seeing our first Hispanic Supreme Court justice (not counting Benjamin Cardozo). While this moment should have belonged to Miguel Estrada—who was denied even a vote by an unprecedented Democratic filibuster—we should nevertheless celebrate Sonia Sotomayor’s rise from very humble beginnings to reach the highest court in the land. Although her selection represents the very worst of racial politics—she is not a leading light of the judiciary and would not have been considered had she not been a Hispanic woman—her career achievements show that the American Dream endures.

What makes the American Dream possible, however, is the rule of law, which in this country is ultimately guaranteed by the Constitution. The Constitution provides for a very specific government structure, with checks on each branch’s powers designed to maximize liberty and eliminate arbitrary and capricious rule. To that end, officers of the judicial branch—judges—are to make their decisions irrespective of the race, religion, or riches of those who come before them. And judges are to interpret the Constitution as written text. If they set aside the text and rule based on their own notions of fairness, then they act as unelected legislators or, worse, extra-constitutional amenders of our founding document.

Nominee Sotomayor knew all this, which is why the testimony she gave at her confirmation hearings disclaimed many of her previous speeches and writings, even going so far as to reject President Obama’s “empathy” standard—the idea that a judge applies the law differently when a litigant is sympathetic in some politically correct way. While she was evasive most of the time—reason enough to vote against her—when she did say something about judicial philosophy, it was often indistinguishable from the words of John Roberts or Samuel Alito (as evidenced by the frustration of left-wing commentators). And for good reason: in poll after poll, the American people overwhelmingly support a vision of the judicial role as one of enforcing the law as written, not of imposing their own policy preferences or vision of justice.

Kudos from this exercise go to those Republicans whose hard questions and thoughtful statements elevated the discussion of the Constitution beyond mere abstractions, so Americans could better understand the significance of ideological differences over the judicial role, or the use of foreign law in interpreting the Constitution, or property rights, or employment discrimination. In walking away from so many controversial positions, Sonia Sotomayor established a new standard to which all future nominees will at least have to pay lip service. While confirmation was almost a foregone conclusion from the start because of the Democrats’ strong Senate majority, the Republicans played well the cards they had been dealt by engaging in a serious discussion about constitutional interpretation and jurisprudential philosophy.
